Your task is to find/explain the following components of this assembly file.

 int source[] = {3, 1, 4, 1, 5, 9, 0}; int dest[10]; int main ( ) { int k; for (k=0; source[k]!=0; k++) { dest[k] = source[k]; } return 0; }

.data source: .word 3 .word 1 .word 4 .word 1 .word 5 .word 9 .word 0 dest: .word 0 .word 0 .word 0 .word 0 .word 0 .word 0 .word 0 .word 0 .word 0 .word 0 .text main: addi t0, x0, 0 la t1, source la t2, dest loop: slli t3, t0, 2 add t4, t1, t3 lw t5, 0(t4) beq t5, x0, exit add t6, t2, t3 sw t5, 0(t6) addi t0, t0, 1 jal x0, loop exit: addi a0, x0, 10 add a1, x0, x0 ecall # Terminate ecall

Questions

a. The register representing the variable k.
b. The registers acting as pointers to the source and dest arrays.
c. The assembly code for the loop found in the C code.
d. How the pointers are manipulated in the assembly code.
